Personally, I really like the cabinet side art shown by JJP. In addition, I like the idea of different side art such as that created by Aurich. What, to me, doesn't fit in Aurich's mock-up is the ruby red color on the rails and legs. I think JJP has it right - silver/plain for the standard hardware and the special bronze (or whatever it is called) on the LE. That color fits the theme totally - sorta like ruby read and emerald green fit WOZ.
I like the pale orc on the right side - excellent character in the movies. I dislike the goblin king completely, simply because he has what I consider a very inconsequential part in the 3 movies (not because he has a scrotum for a chin!)... and reminds me of jar jar binks somewhat.
Would it be incredible if THLE had unique cabinet side art? Absolutely. Would it be awesome if it featured Smaug or something else unique? Absolutely. If the LE has the same cabinet art as the standard, I'm ultimately fine with that. I'm not looking at the side art anyway when I'm playing, and half the side art will be blocked by my LOTR (I'll probably put the LOTR on the goblin king side!!). I'm significantly more interested in the playfield, the game play, the LCD, flow, rules, etc.
Very excited to see the full layout during Expo - very much looking forward to pics. Perhaps we will all be surprised. Regardless, not everyone will be happy at the end of the day - that's not a bad thing since there are other pin manufacturers out there.
And yes, I'm in on THLE. It'll be my first NIB and my second pin.
